Police said they are trying to determine if a Ford F-150 pickup truck found near the crime scene is connected to Jerrell.

According to a press release from the Shepherdsville Police Department, a woman was questioned by police and was later released after consultation with the Bullitt County Commonwealth Attorney's Office. No charges have been filed.

For many drivers traveling from Indiana, the rest area is the first stop they will make in Kentucky.

"It's a convenient spot to get out, take a break, stretch and easily get back out and go south on 65 again," Bernardi said.

Raymond Logsdon, who witnessed the traffic backup, is currently living out of his car. He said others use the rest area as a temporary place to call home.

"Some of the people are between jobs, or trying to find jobs, and they stay here," he said. "It's kind of like a family around here."

Authorities were questioning potential witnesses Saturday afternoon. Several truck drivers were asked to stay put during that time.
